Answer:

14 - 4n

Step-by-step explanation:

g = 4n+1/n

n = 1/g−4

---------------------------------------

h = −2n+3/n

n = 3/h+2

---------------------------------------

g(- n + 3) = 4(- n + 3) + 2 = - 4n + 12 + 2 = 14 - 4n

What is the scale factor of the dilation? Help please

DaniilM [7]

Imagine A'V' is part of the dilated figure, and AV is part of the original figure.

A'V' = 3.2

AV = 3.2 + 4.8 = 8

A'V'/AV = 3.2/8 = 2/5

Answer: First choice, 2/5.

Use the "mixed partials" check to see if the following differential equation is exact. If it is exact find a function F(x,y) who

Arturiano [62]

We have

$(-3xy^2+y)_y=--6xy+1$

and

$(-3x^2y+x)_x=-6xy+1$

so the equation is indeed exact. So we want to find a function $F(x,y)=C$ such that

$F_x=-3xy^2+y$

$F_y=-3x^2y+x$

Integrating both sides of the first equation wrt $x$ gives

$F(x,y)=-\dfrac32x^2y^2+xy+f(y)$

Differentiating both sides wrt $y$ gives

$F_y=-3x^2y+x=-3x^2y+x+f_y\implies f_y=0\implies f(y)=C$

So we have

$F(x,y)=-\dfrac32x^2y^2+xy+C=C$

$F(x,y)=\boxed{-\dfrac32x^2y^2+xy=C}$

vfiekz [6]

Answer:

( -2,5)

Step-by-step explanation:

To find the x coordinates of the midpoint, add the x coordinates of the endpoint and divide by 2

( -9+5)/2 = -4/2 = -2

To find the y coordinates of the midpoint, add the y coordinates of the endpoint and divide by 2

( 3+7)/2 = 10/2 = 5

The midpoint is ( -2,5)
